Its about time. There are many reasons, firstly at start of dungeon having activate is annoying. Secondly, there is no longer a need to Tank Stance with Enimity/Def up/Attack down. Thirdly, multi-tank run arent really a thing anymore.

IF you want to bring back Tank Stance to buff/Debuff again, I'll listen.

Enimity Mitigation can be handle with Shirk. Decrease recast time and that's solve the issue.
